"No, I don't understand why that's come about!" he laughed. "It's crazy. It's like those other weird rumors. I mean, I wish!"

He also debunked the Star Wars Hans Solo spin-off rumors.

"I didn't even know there was a Hans Solo spin-off!" he said. "It sounds like a cool spin-off though -- I'll watch it."

Pattinson plays Rey in The Rover, who becomes an unwitting accomplice to Eric, a ruthless, hardened ex-soldier (Guy Pearce) in a post-apocalyptic world. He's currently getting rave reviews for his bold new role, including from his co-star Guy Pearce.

"Rob does a beautiful job as Rey. He really has a beautiful vulnerability and a naive sort of quality that he brought to Rey, which I think really works for our dynamic," Pearce, 46, told ET. "He's a really committed actor."

Director David Michod revealed that Pattinson's audition was "amazing" and "exhilarating," and that he had not seen any of the Twilight films prior to meeting him.

"I didn't feel like I needed to. I saw everything I needed to see in that audition," he said. "I had met him before and really liked him. He's really smart, and has a kind of delightful availability, you know? So I had all the info I needed."
